BEVETMENT.

application' fried ma@ aa, 1.925. serial No. saves.

This invention relates to a mattress or revetment for the protection of the banks oft rivers, streams or other bodies of water from erosion caused by currents, wave action or other wash, and toy also guard against suriace or bank wash due to the seepage or flow of surface waterfrom the bank behind the revetment into the stream.

One of the objects of the invention is to produce a revetment which may be assembled on shore and left in position to fall into place as the vground is eroded Jfrom below same, or which may be fed od a barge or the like as common` in the art.

j Another' object is to produce a revetment formed of a combination of live willows, cottonwood or otherl flexible mat material and weights, such as concrete blocks, so related and tied together that they mutually cooperate to maintain their respect-ive positions and in which thevweights project below the mat for some distance and thereby form auxiliary anchors by embedding` themselves in the bottom of the stream, and the possibility of a current of waterv projecting itself between the mat and a block and tearing the latter loose is thus entirely obviated.

A which is flexible in all directions and which will automatically assume a position vconforming to the irregularities of the bank. sinking deeper to take care of the scour ot the river or of a surface wash from behindv the mat; vitbeing understood that the mat is so constructed that the concrete blocks are protected from contact one with another by the interposition ont the mat as'willhereinaft'er appear. f i o.

. Another object is to producea revetment of the general character outlined which is of strong, durable, eflicient and comparatively inexpensive construction, and in order that it may be fully understood7 reference is to be had to the accompanying drawing, in

l which Figure 2 is a section on the line lig-IT of Figure l.

Figure 3 is modified orm of construction for use above the water like where the mat is alternately subjected to submersion and exposure to the still further object is to produce a mat an elevation of a Slightly.v

air, or is practically continuously exposed n on the line IV-,IV`

to the air. Y

Figurey t 1s a sect1 of Figure 3. Y

In the said drawing where like reference characters identify corresponding parts in all of the figures, weights 1 of any suitable material, such as concrete blocks, and preferably slightly more than twice `as long as they are square, are employed for the weighing down and anchoring of a willow or other suitable mat,

The blocks l are preferably cast' of concrete and vinset in each block and having projecting eyes or other means of attachmentis a pair of eye-bolt rods 2 and 3, or

looped wire vcables or similar means, the Y connections being respectively located about one-third the length of the block from itsI opposite ends and extending at-right-angles the ground, are connected in parallel rows at right angles by wire ropes, cables or rods 41, all of equal length. Itwill be understood that'the blocks may be cast with cylindricalpassageways through which cables are threaded, the blocks being secured by clamps secured to the cables.Y f

Ala-yer of live willows, planks or the like 5 is now compacted between the blocks and upon the cables@ and a second' layer of willows 6 is laid and compacted between the blocks and crosswise of the willows 5, it beingv understood that this filler may be of any suitablematerial yaccording to the nature of the work. The other connections 3, of theblocks are now'connectedto'gether by wires, ropes, 'cables-orrods 7 compressing and compactingthe willows in position, it being understood that the cables 7 will be equal in length tothe cables 4. y

The revetment as a whole is now completed and may be anchored by a series of cables 8 to a post 9 set in the bank and leftin position to settle, or may becarried out inthe stream and fed into position off the ends of barges as common in the art.

It will'be apparent Jfrom a consideration of the drawing and the above description` that the distance between the concrete blocks and the proportions of the blocks may be varied according to the number of pounds per square foot it is desired to construct the vmat, and that each block is held reliably in position by its connecting cables and is protected from contact with the adjoining blocks by the interposed mat. It will also be apparent that the mat is reliably secured between the cables l and 7.

It will also be apparent that as the blocks project some distance below the mat their projecting ends by embedment in the bottom of the stream will aid materially in anchoring the mat in position and that there is no chance for a current of water to tear a block loose without the strain being spread over practically the entire area oi the mat.

In Figures 3- and 4 a` slightly modified construction is illustrated for use -above the waterline. In such an exposed position Willows and cottonwoods will soon rot. The concrete blocks and their connecting cables t and 7 are disposed as above described, but in place of the willow mat, suitable woven wire sections l0 or similar flexible materials are connected at opposite ends to the cables 2 by means of clips ll and at their other opposite ends or edges are connected to each other by the clips l2. In'order to still further secure the vwoven Wire sections in position it may also be desirable to embed eyes 13 in the corners of the blocks l as illustrated, to which the corners of the wire sections l0 are secured by suitable fasteners 14.

A mat constructed as just described will function' in all respects as does the willow mat, as the woven wire 10 will be sufficiently fiexible to accoi'ninodate itself to the ir regularities of the bottom of the stream.

l? rom the above description, it will be apparent that I have produced a device of the character described which possesses all the features of advantage set forth as desirable; and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly falling within the spiritvand scope of the appended claims.

I claim:

l. A revetrnent comprising a plurality of weights spaced apart in parallel rows in both directions, each weight being connected to all adjacent weights, and flexible mat material bridging the spaces between the weights.

2. A revetment comprising a plurality of weights spaced apart in parallel rows in both directions, connections between each weight and the adjacent weights, and fleXible mat material bridging the spaces between the weights and held in position by the connections between the weights.

8. A revetment comprising a plurality of weights spaced apart in parallel rows in both directions, connections between each weight and the adjacent weights, and flexible mat material bridging the spaces between the weights and held in position by the connections between the weights; said weights projecting below the plane of the mat for einbedment in the bottom of the stream.

4,.. A revetment comprising a plurality of weights spaced apart in both directions to form two series of parallel rows at right angles to each other, connections between adjacent weights of one 'series of parallel rows, a series of mat-s resting on said connections, and a second set of connections between adjacent blocls and overlying 'the inat and extending at right firstnamed connections.

5. Arevetment comprising a plurality of weights spaced apart in both directions to form two series of parallel rows at right angles to each other, connections between adjacent weights of one series of parallel rows, a series of mats resting on said connections and atricfht angles thereto, a. series of mats upon said first-named series of mats and at right angles thereto, and a second set of connections between adjacent weights and overlying the second mat and extending at right angles to said mat.

6. A revetment comprising arplurality of weights spaced apart in parallel rows, means securing said weights together, and a filler between the parallel rows of weights and held in position by said securing means.

In witness whereof I hereunto afiix myl signature.
